Bent section structure of spillway discharge chute
The invention relates to the field of discharge chutes, and provides a bent section structure of a spillway discharge chute. The bent section structure comprises at least one buffer section and at least one contraction section, and the buffer sections and the contraction sections are arranged at intervals and are in smooth connection; and the section widths of the buffer sections are equal, and the section width of the contraction section in the midstream is smaller than the section widths of the contraction sections in the upstream and the downstream. The bent section structure of the spillway discharge chute is suitable for a bent shoreside type spillway, after water flow enters the contraction section, due to the fact that the section width of the contraction section in the midstream is smaller than the section widths of and the section width of the contraction sections in the upstream and the downstream, restraining force is applied to the water flow through the contraction section, and the water flow is gathered in the center line direction firstly, and after flowing through the midstream, lateral flow is gradually generated under the action of gravity to realize redistribution, so that the water flow in the discharge chute is more uniform, and the flow state of the water flow in the discharge chute is improved.
本发明涉及泄槽领域，提供了一种溢洪道泄槽弯段结构，其包括至少一个缓冲段和至少一个收缩段，缓冲段与收缩段互相间隔设置且平滑衔接；其中，缓冲段的断面宽度相等，收缩段在其中游的断面宽度小于其上游和下游的断面宽度。该溢洪道泄槽弯段结构适用于弯曲岸边式溢洪道，水流进入收缩段后，由于收缩段在其中游的断面宽度小于其上游和下游的断面宽度，通过收缩段向水流施加约束力使得水流先向中心线方向聚集，直至流过中游后在重力作用下逐渐产生侧向流动实现再分配，使得泄槽内水流更加均匀，从而改善泄槽内水流的流态。
